that's the problem, actually.  all communication with xfce-mcs-manager 
is one-way.  the client apps (e.g., xfdesktop) can say "hey mcs manager, 
gimme the setting named X in channel Y," but that's basically all it can 
do.  building in a hook/callback mechanism would be a bit of an 
undertaking, and probably not worth the effort.  hopefully 
xfce-mcs-manager will go away in favor of something DBUS-based for xfce 
4.4 anyway.

at any rate, it seems to work fine just setting a property on the root 
window in xfdesktop and reading the property in the mcs plugin, so i see 
no need to mess with it.
